The Beilstein is a basalt cone with the largest basalt cave in the Main-Kinzig district. The formation was formed by volcanic eruptions 10 to 20 million years ago; the surrounding red sandstone, which otherwise characterizes the Spessart, is around 200 million years older. The basalt breach was exposed by erosion; The typical basalt columns and smaller, spherical structures can be seen on the rock walls. On the mountain, which was first mentioned in a document in 1059, are the remains of the small, medieval hilltop castle of Beilstein. It was built to protect the possessions of the archbishopric of Mainz and to control an old road, and was first mentioned in 1343. It was also intended to protect the first glassworks that were established. When rule passed to the Counts of Hanau, the castle probably lost its importance and has since fallen into disrepair. Due to the poor source situation, little is known about the castle. Source: Wikipedia

The Beilstein is a mountain in the Spessart, 499.5 m above sea level (NHN). It lies east of the road from Bad Orb to Jossatal, between Villbach and Lettgenbrunn, within the municipality of Jossgrund in the Main-Kinzig district of Hesse. The Beilstein is a basalt cone with the largest basalt cave in the Main-Kinzig district. The formation originated 10 to 20 million years ago through volcanic eruptions; the surrounding Bunter sandstone, which otherwise characterizes the Spessart, is around 200 million years older. The basalt breakthrough was exposed by erosion; the rock faces show the typical basalt columns as well as smaller, spherical formations. On the mountain, first documented in 1059, are the remains of the small, high medieval hilltop castle Beilstein. It was built to protect the possessions of the Archbishopric of Mainz and to control an old road, and was first mentioned in 1343. Furthermore, it was intended to protect the first glassworks that were established. When the lordship passed to the Counts of Hanau, the castle presumably lost its importance and fell into ruin thereafter. Due to the scarce sources, little is known about the castle. Today, the complex consists only of a ring wall about 12 meters long. Source: Wikipedia

A beautiful heathland in the Spessart is more of an exception. An important place for our (species) nature conservation
